Struct SimulatedNodeProvider 

pub struct SimulatedNodeProvider;

A NodeProvider that does not talk to any real cluster substrate: it simply reports every requested node as provisioned/terminated.

Exists so callers that want to exercise AutoScaler’s scaling decisions end to end (benchmarks, demos, tests) can opt into that explicitly, instead of AutoScaler silently fabricating success with no substrate attached at all. Never attach this where scaling is expected to have a real effect on a real fleet.

Implementations

impl SimulatedNodeProvider

pub fn new() -> Self

Trait Implementations

impl Clone for SimulatedNodeProvider

fn clone(&self) -> SimulatedNodeProvider

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Copy for SimulatedNodeProvider

impl Debug for SimulatedNodeProvider

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for SimulatedNodeProvider

fn default() -> SimulatedNodeProvider

Returns the “default value” for a type.

impl NodeProvider for SimulatedNodeProvider

fn provision_nodes(&self, count: usize) -> Result<usize>

Request count additional compute nodes. Returns the number that were actually provisioned – implementations must not report more than what was genuinely started, and may return fewer than count if capacity is limited.

fn terminate_nodes(&self, count: usize) -> Result<usize>

Terminate count compute nodes. Returns the number that were actually terminated.
